British Rail's second generation of Standard Coach design is known as the Mark 2. Design and construction followed on from the universal and ubiquitous Mk1 family of coaching stock, with the prototype example built in 1963. Series production continued until 1975 at Derby Carriage Works. They were of steel construction, and of a more monocoque design than the Mk1, which added to their safety and integrity in event of collision or mishap.
As passenger expectations and railway operations had moved on since the vast Mk1 range was conceived, and because there was still much life left in the Mk1s by the mid-sixties, a much reduced number of vehicle types were built. The basic Mk2 types included First and Second class accommodation, with corridors and compartments only available to First Class passengers, all Second Class coaches were conceived as open saloons. First and Second class Brake coaches were built, but no full brakes, catering cars, restaurants, buffets or sleeping cars were included, Mark 1 coaches fulfilling these needs until Mark 3s came along in the late seventies.
